Lustre Re-Fire Advice Please

[Emma Jo]

Hello!

 

I have only been working with ceramics for a year and I am mostly self taught  / researched. For what i do it works well enough for me, but i have recently hit a snag and i can't seem to find the right info online anywhere - I wonder if anyone can help me.

 

I applied gold lustre to an earthenware pot recently, When i took it out of the kiln a small patch of the black underglaze had chipped off This happens quite frequently with this particular glaze its usually a small section that pops off and I unusually re-fire to cone 04 for a small repair and its just fine. 

 

I am guessing I cant re-fire the chip area to cone 04 now as I have applied the gold lustre, If I do go ahead and repair the chip will the gold lustre just burn away?

 

If it does, will it leave the surface area intact for re-applying the gold lustre and re-firing. It sounds like a waste of time, but I would really like to save this pot as best I can before giving up and re-making from scratch. 

 

Does anyone know what it might be best for me to do?

Thank you!

I think you may have to clean the luster surface after firing to 04. It maybe be a product from the Lusterware producers, but it is the same liquid you are suppose to use before applying luster originally.

If you can call the product company for specific instructions. Medmar, or there.

Medmar is long out of business-Duncan seems to be the last lustar Co. in US.

They sell a cleaner
